Practice Makes Perfect

Garrus believes that, besides sniping, he isn't very good at anything. He especially thinks he isn't good enough for Shepard. Can Shepard change his mind? Can a little practice, especially at accepting himself, help Garrus win Shepard's heart? *Not totally Garrus centered, it will be from Shepard's pov as well... Rating for cuss words but no worse then what is in the game*
